I am continuing to work with the developer of Maps Pro to figure out what exactly the problem I am having with it. I think they are trying to create something useful but it may not get to where we want as a replacement for S&T. So far I am thinking MS MAPS still gives more detail as an OFFLINE map. I will keep fooling around with these to try to find one that easily allows adding waypoints to force a route. One positive thing about Maps Pro is the developer does keep responding to emails - I think it is a woman and I think she is in France. She is working on the entire world and has some of it done in Chinese - as well as other languages. I have no idea how they do this stuff.
She says she expects to have Mexico working within a week or so.
